Electromagnetic Compatibility Benchmark-Modeling Approach for a Dual-Die CPU

The traditional challenging problem 2000-4 of electromagnetics (as indicated by the IEEE) proposed a benchmark model of a conventional CPU with a heatsink. However, after CPU entered the multiple-die century, the original model is no longer effective for the new generation multiple-die package. A novel model is proposed in this paper for electromagnet radiation modeling of the CPU with dual dies as a new electromagnetic compatibility benchmark-modeling approach. The modeling method is validated by the measurement, and the simulation and measurement results showed a good agreement, and demonstrated it is an effective modeling technique.
